Clinical examinations revealed a massive hepatic lesion exceeding 10 cm in diameter, accompanied by elevated eosinophils (0.90 × 10<sup>9</sup>/L) and basophils (0.08 × 10<sup>9</sup>/L). Despite undergoing liver transplantation, the patient succumbed postoperatively. Histopathological confirmation and molecular phylogenetics identified the Mongolian genotype of E. multilocularis infection, distinct from the predominant Asian genotype in China. Potential evidence of zoonotic transmission was discovered through genotype-matched E. multilocularis detection in corsac fox (Vulpes corsac) feces from the grasslands along the shores of Hulun Lake (Hulun Buir City, northeastern Inner Mongolia, China).</p><p><strong>Conclusions: </strong>This report provides the primary evidence of a locally acquired human AE infection in China caused by the Mongolian genotype of Echinococcus multilocularis. The discovery of this case challenges historical classifications of echinococcosis endemic areas. The findings call for revised AE-endemic identification criteria, improved AE diagnostic protocols, and enhanced AE surveillance in the Inner Mongolia region to generate further epidemiological evidence and information on disease progression.</p>","PeriodicalId":48820,"journal":{"name":"Infectious Diseases of Poverty","volume":"14 1","pages":"74"},"PeriodicalIF":5.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12288280/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144709611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As MDA-azithromycin to reduce mortality is considered for expansion to more settings and populations, care must be taken to maximize benefits and reduce risks (e.g., antimicrobial resistance or AMR) of this intervention.

We included trials for which azithromycin was administered for the prevention or treatment of a disease or condition that was not explicitly diagnosed or necessary for participant inclusion, and for which treatment was randomized by geographic units.

New evidence suggests the benefits of widening the target age group and the persistence of mortality benefits in settings with competing interventions. Published practices to ensure geographic separation of communities in different treatment arms to reduce spillover effects were not customary. We found information on AMR monitoring practices for just over half the trials (16/30).
